The electronic structure of the xenon insertion compounds XXe-MX2 (XÂ =Â F, Cl, Br, I; MÂ =Â B, Al, Ga)

Nature of chemical bonding in the XXe-MX2 (X = F, Cl, Br, I; M = B, Al, Ga) molecules have been investigated using topological analysis of ELF and electron density. The xenon-icosagen bond, Xe-M displays covalent nature in all studied molecules, confirmed by bonding disynaptic attractor V(Xe,M) for the ELF field with basin population ranging from 1.1 to 1.8e.24
